The 90% confidence interval to estimate the average attendance of a college men's basketball game during the last season is from a lower limit of _ to an upper limit of _.
b. What assumptions need to be made about this population?
Explanation / Answer
The statistical software output for this problem is:
One sample T summary confidence interval:
? : Mean of population
90% confidence interval results:
Hence,
a) 90% confidence interval:
Lower limit = 4376.997
Upper limit = 5889.003
b) Assumption: Since the sample size is less than 30, we must assume that the population is normally distributed.
